Santini, who works at Union City High School in Hudson County, was found by an officer sitting in his car with the woman in the parking decks on Challenger Road in Ridgefield Park.

When the officer went to investigate, Santini allegedly reached for a plastic bag in the center console. Authorities say he ignored commands to stay in his car, exiting the vehicle before pushing the officer.

After a struggle, police say Santini was brought under control and handcuffed.

During the arrest, the female fled on foot from the scene. She was later located.
